EQUIPMENT: Chain (steel or cloth tape measure), Keil (surveyor crayon), Field Book, Pencil OBJECTIVE: To determine the length of student’s natural pace DIRECTIONS: The purpose of this lab is for the student to determine the actual length of his/her pace so that he/she may in future years use this knowledge in rough checking and in measurement. The best method is for the student to walk his/her natural pace rather than trying to create artificial two foot or three foot paces. In going downhill, the natural tendency is to take longer steps unless the hill is quite steep and short steps are necessary to prevent falling. PART 1 1.The instructor will mark out 100 foot lengths, using keil marks as the beginning and end points. 2.Each student will walk the 100 foot length 4times, counting the amount of steps taken each time. RECORD ALL MEASUREMENTS IN THE FIELD BOOK.3.The student will calculate the average length of pace (feet per step) on the left hand page of his/her field book by averaging field measurements, then dividing 100ft by average number of steps.4.The student will draw a sketch on the right hand page and will include the information from the field book checklist. PART 2 1.The instructor will measure and mark a rectangle on the ground.2.The student will pace around the designated rectangular area twice, counting the amount of paces per each side. DRAW A SKETCH AND RECORD ALL MEASUREMENTS. 3.The instructor will then inform the students of the actual dimensions of the rectangle. 4.The student will determine their measured dimensions of the rectangle by averaging the # of paces per side, then multiplying that value by the pace determined in Part 1. The student will then calculate the percent error of each side as well as the area of the rectangle. percent error=[field measurement value-actual value]/actualvaluex100%5.The student will provide a write-up detailing the process, accuracy and precision of this method and a comparison to other methods of measuring. Show all computations and data in the field book. Field notes are to be attached to the write-up. All pertinent data must be properly recorded in the field book. Deliverables(individual lab report): 1.Written report (about 1-2 pages 1.5 line spacing) containing: a. Introduction/Procedure –Explain why pacing is used and how you performed lab b. Calculations –all calculations shall be included (can be hand-written or typed). c. Summary/Discussion –explain what you learned and briefly compare the accuracy of pacing to other types of measurements. d. Field notes
Requirements: 3 pages with the data and the sketches
